Application February 15, 1946, Serial No. 647,848

My invention relates to burners of oil and more particularly to housing for such burners.

The object of my invention is to eliminate common difliculties arising in the use of most oil burners.

One of these difiiculties is the occurrence of" excessive smoke and soot. The cause of this difiiculty is usually found in an inadequate air supply, causing faulty combustion. Another of the difficulties referred to is caused by the admission of an excessive amount of air producing a flame looking and sounding like the flame of a blow-torch, indicating a waste of fuel. Other difiiculties commonly arising consist in noises created either by the mechanical equipment of the burner or by the velocity of the air taken in for combustion. A further difficulty lies in the escaping of combustion odors from the burner into the house to be served by the heater.

As stated above, the object of my invention is to overcome and eliminate these and other difficulties not especially mentioned.

Other objects of my invention may appear in the following specification describing my invention with reference to the accompanying drawing illustrating a preferred embodiment of my invention. It is however to be understood that my invention is not to be limited or restricted to the exact construction and combination of parts described in the specification and shown in the drawing, but that such changes and modifications can be made which fall in the scope of the claim appended hereto.

In the drawing:

Figure 1 is a vertical longitudinal sectional view of a housing according to my invention attached to a heater, some of the parts being shown in elevation, and

Figure 2 is a front view of the housing shown in Figure 1.

Referring now in detail to the drawing the burner housing according to my invention has a top wall II), a front wall II and two side walls I2. These walls are preferably made from one piece of metal, so that the housing is open on the back and the bottom. The front Wall has an outwardly extending flange I3 on its bottom edge. The top wall I has an upwardly extending flange I4 on its rear edge and the side walls have each an outwardly extending flange I5 on their rear edges.

In the front wall I I a comparatively large door opening is provided and a door I6 is pivotally attached to the front wall I I by means of hinges I I. A plurality of latches I3 is rotatably fastened to the front wall II adjacent the free ver- 1- Claim. (01. 158-28) tical edge of the door It and these latches are adapted to engage the free edge of the door and hold the door in closed position. To assure an air tight closure between the door and the front .wall a rubber gasket I9 is attached to the door I6.

This housing is arranged so that it will enclose the burner mechanism 20, and so that the flanges I4 and'I5 will abut the front wall of the heater 2| and the flange I3 will rest on the floor on which the heater stands. These flanges are fastened to the heater by means of bolts 22 and to the floor by anchor bolts 23. The burner mechanism 20 includes a burner tube 2 which projects through a burner entrance opening 3 provided in a side wall 4 of an oil burning furnace ZI. Surrounding the burner tube 2 and sealingly closing the burner opening is a sealing means or cover 5. The burner 28 is also provided with an air intake 6.

The top wall II] of the housing has a hole 24 therein surrounded by an upwardly extending ring-flange 25. A pipe .26 engages this ringflange and leads to the outside atmosphere as indicated at 21 in Figure 1. In the pipe 26 a normally closed damper 28 having a counterweight 28 on its lower end is swingingly arranged and on the outside end of the pipe a screen 29 is provided to prevent insects, moths or the like from entering the pipe.

A handle 30 is attached to the door I6 adjacent the free vertical edge thereof.

The hole 24 in the top wall II] of the housing is located directly above the air intake of the burner. Normally the counter-weighted damper 28 closes the pipe 26, but the draft created by the burner overcomes the counter-weight on the damper and opens it. In this manner air needed for perfect combustion will be conducted from the outside atmosphere through the pipe 26 into the housing and into the burner, and the air in the basement or other room in which the heater is located will not be deprived of oxygen, so that a healthier condition is obtained.

The above description shows clearly how the housing according to my invention prevents the forming of excessive smoke and soot by furnishing a sufiicient flow of fresh air to the burner. Since this flow of fresh air is automatically regulated by the need of the flame for fresh air an over-supply of air is eliminated so that the creation of a flame looking and sounding like a blow-torch flame is prevented.

Any odors of combustion can not escape into the house served by a burner equipped with a housing according to my invention.

The housing will deaden any noise created by the mechanical equipment of the burner or by the velocity of the air taken in for combustion. This deadening effect may be improved by painting the inside of the housing with a sound-insulating paint, for instance such as Dum-Dum paint.

Having described my invention what I claim and desire to secure by Letters Patent is;

In combination, a room containing a closed furnace having a sidewall formed with a burner entrance opening, a closed imperforate burner housing having an open end engaged with and closed by said furnace sidewall, said housing surrounding said burner opening, an oil burner within said housing having a burner tube projecting through said burner opening, mean surrounding said burner tube and closing said burner opening, ,said burner having an air intake, said housing having a wall formed with an air inlet openin located in the region of said burner air intake, an air pipe leading from the atmosphere outside of said room to said air inlet opening, and a normally closed damper in said air pipe arranged to be opened by a draft developed in said housing and in said air pipe by operation of said oil burner.
